Question: Who ruled Egypt in the Fourth Dynasty? Passage:Azurite is unstable in air, however it was used as a blue pigment in antiquity. Azurite is naturally occurring in Sinai and the Eastern Desert of Egypt. It was reported by F. C. J. Spurrell (1895) in the following examples; a shell used as a pallet in a Fourth Dynasty (2613 to 2494 BCE) context in Meidum, a cloth over the face of a Fifth Dynasty (2494 to 2345 BCE) mummy also at Meidum and a number of Eighteenth Dynasty (1543–1292 BCE) wall paintings. Depending on the degree of fineness to which it was ground, and its basic content of copper carbonate, it gave a wide range of blues. It has been known as mountain blue or Armenian stone, in addition it was formerly known as Azurro Della Magna (from Italian). When mixed with oil it turns slightly green. When mixed with egg yolk it turns green-grey. It is also known by the names blue bice and blue verditer, though verditer usually refers to a pigment made by chemical process. Older examples of azurite pigment may show a more greenish tint due to weathering into malachite. Much azurite was mislabeled lapis lazuli, a term applied to many blue pigments. As chemical analysis of paintings from the Middle Ages improves, azurite is being recognized as a major source of the blues used by medieval painters. Lapis lazuli (the pigment ultramarine) was chiefly supplied from Afghanistan during the Middle Ages, whereas azurite was a common mineral in Europe at the time. Sizable deposits were found near Lyons, France. It was mined since the 12th century in Saxony, in the silver mines located there.

Question: Did the Confederate States Navy have a lot of gunboats? Passage:The opening phase of what came to be called the Burnside Expedition, the Battle of Roanoke Island was an amphibious operation of the American Civil War, fought on February 7–8, 1862, in the North Carolina Sounds a short distance south of the Virginia border. The attacking force consisted of a flotilla of gunboats of the Union Navy drawn from the North Atlantic Blockading Squadron, commanded by Flag Officer Louis M. Goldsborough, a separate group of gunboats under Union Army control, and an army division led by Brig. Gen. Ambrose Burnside. The defenders were a group of gunboats from the Confederate States Navy, termed the Mosquito Fleet, under Capt. William F. Lynch, and about 2,000 Confederate soldiers commanded locally by Brig. Gen. Henry A. Wise. The defense was augmented by four forts facing on the water approaches to Roanoke Island, and two outlying batteries. At the time of the battle, Wise was hospitalized, so leadership fell to his second in command, Col. Henry M. Shaw.

Question: How old was the director of The Green Mile when it was made? Passage:Director Frank Darabont first read Stephen King's 1980 novella The Mist in the Dark Forces anthology, and originally expressed interest in directing a film adaptation for his directing debut. He instead filmed The Shawshank Redemption, also based on another King novella. In October 1994, after completing The Shawshank Redemption, Darabont reiterated his interest in filming The Mist. Darabont did not immediately follow through, instead directing the 1999 film adaptation of Stephen King's The Green Mile. Darabont eventually set up a first look deal for The Mist with Paramount Pictures, having been entrusted feature film rights by Stephen King. By December 2004, Darabont said that he had begun writing an adapted screenplay for The Mist, and by October 2006, the project moved from Paramount to Dimension Films, with Darabont attached to direct and actor Thomas Jane in negotiations to join the cast.
